Mercury Gigabit Ethernet Switch Overview | Generated by AI
Question: Introduction to Mercury switch: 5 port, 1000Mbps, model 5G105C, dark color, 5V, 0.4A
Answer:
The query appears to refer to a 5-port Gigabit Ethernet network switch from the Mercury brand (or similar generic brands sold as “Mercury”), likely model SG105C or a variant like SG105M/MS105G, with specifications including 5 ports supporting up to 1000Mbps (Gigabit), powered by a 5V adapter (some models around 0.4A-0.6A), and possibly in a dark (black or gray) casing.
Overview
Mercury is a budget networking brand (often associated with generic Chinese manufacturers or rebranded Mercusys/TP-Link sub-brands) that produces affordable unmanaged desktop Ethernet switches. These are compact, plug-and-play devices designed for home or small office use to expand wired network connections.
Key Features (based on common models like SG105C/SG105M/MS105G)
- Ports: 5 × RJ45 Ethernet ports, auto-negotiation supporting 10/100/1000Mbps (Gigabit speeds).
- Type: Unmanaged switch – no configuration needed; simply plug in and use.
- Performance: Store-and-forward switching, full-duplex operation for up to 2000Mbps per port theoretically, with MAC address table of ~2K entries.
- Power Supply: External adapter, typically 5V DC with current around 0.4A–0.6A (power consumption low, ~2-3W max).
- Design: Compact desktop form factor (often plastic casing in black/dark color), fanless for silent operation.
- Additional: Auto MDI/MDIX (no need for crossover cables), energy-efficient (adjusts power based on link status/cable length), LED indicators for power and port activity.
- Standards: Compliant with IEEE 802.3, 802.3u, 802.3x, 802.3ab.
Usage
This switch is ideal for connecting multiple devices (e.g., computers, printers, gaming consoles, smart TVs) to a router for faster, more stable wired connections compared to Wi-Fi. It supports high-speed file transfers and streaming at Gigabit speeds when all devices and cables (Cat5e or better) are compatible.
Note: “Mercury switch” here refers to the brand name, not the toxic tilt-switch type containing liquid mercury (which is unrelated and largely phased out due to environmental concerns).
